A Phase Ib/II Dose-finding Study of DDFPe in Patients With Acute Ischemic Stroke
Stroke is the fifth leading cause of death in the United States and is the leading cause of long term disability. Distinct geographic disparities in stroke mortality, with highest rates in the southeast United States including Arkansas, are known as the "stroke belt." There the average stroke mortality is ≈20% to 40% higher than the rest of the nation. Stroke is the leading cause of serious long-term disability. Between 2012 and 2030, disability and medical costs related to stroke are projected to triple, from $71.6 billion to $184.1 billion, with the majority of the projected increase in costs arising from those 65 to 79 years of age.
There are two main forms of stroke, ischemic and hemorrhagic. An ischemic stroke occurs in 85% of cases and is caused by cerebral vessel occlusion, obstructing blood flow to a portion of the brain. Currently, the only approved therapies for acute ischemic stroke are IV tissue plasminogen activator (tPA), a thrombolytic agent that clears the thrombus within the blood vessel, or intra-arterial catheter thrombectomy. Despite the availability of therapy, it reaches only approximately 7% of ischemic stroke victims in the United States5. Delay beyond the effective time window for therapy is a common reason for failure.
To reduce the devastating impact of stroke on individuals and society, the investigators continue to seek ways to improve functional recovery and limit ischemic damage in stroke patients. The potential neuroprotective agent, dodecafluoropentane emulsion (DDFPe) has recently shown strong positive effects in pre-clinical animal models of acute ischemic stroke6-11. Other perfluorocarbons have been tested in humans as potential neuroprotectants and blood substitutes yet none have been successful.

Maximum Tolerated Dose (MTD) of DDFPe Evaluated by Number of Dose Limiting Toxicities
Временное ограничение: 12 hours after subjects have had a documented Acute Ischemic Stroke (AIS)
|
The primary objective of this study is to establish the Maximum Tolerated Dose (MTD) of DDFPe given intravenously at intervals of 90 ± 10 minutes x 3 doses within 12 hours after subjects have had a documented Acute Ischemic Stroke (AIS).
The algorithm for determining the MTD is based on the number of subjects who experience a Dose Limiting Toxicity (DLT) in each cohort, as defined in the clinical protocol.
If three or more subjects who received DDFPe in an 8 subject cohort experience a DLT, the MTD will be determined to have been exceeded and further enrollment in the cohort as well as dose escalation will stop.

NIHSS Assessment
Временное ограничение: NIHSS scores were recorded at outside hospitals when appropriate and also at the study center as inside baseline NIHSS score. Repeat NIHSS scores were recorded at 2, 3.5, and 7.5 hours after drug injection and on discharge.
|
The NIH Stroke Scale (NIHSS) is an assessment tool that provides a quantitative measure of stroke-related neurologic deficit.
The NIHSS is a 15-item neurologic examination.
Ratings for each item are scored on a 3- to 5-point scale with 0 as normal.
Scores range from 0 to 42, with higher scores indicating greater severity.

Modified Rankin Scale (mRS)
Временное ограничение: mRS values were obtained on Day 7 or Day of Discharge, Day 30 and Day 90.
|
The modified Rankin Scale is a measure of the degree of disability in patients who have had a stroke with 0 being no symptoms at all to 6 being death.
Thus, a higher score indicates greater severity.

mRS values were obtained on Day 7 or Day of Discharge, Day 30 and Day 90.
